Mountain Lion won't let me install on my HDD?

[drgrafix]

I just downloaded Mountain Lion and wanted to do the upgrade over my v.10.6.8 which I made sure was up to date. Download went smooth, started the install and whn I get to the page where it wants to know where I want to install the OS, I see grayed out photo-icons of my HDD and my external 1TB Lacie which is my Time Machine drive.

My HDD has about 125GB free, so when I try to select it I get a popup saying its used for Time machine backups when its not. I tried re-booting, same deal. What could be holding me up?

Disconnect your external and give it a try. Suggest making a USB thumb drive before running the Installer.

Tried that disconnected ALL external drives did a hard boot, still stuck at same point. Please explain what you mean by making a USB drive the installer. I even turned off Time Machine yet the pop up still appears saying: This disk is used for Time Machine backups.

Go figure.

Thanks Harry but I managed to get it installed this morning by trashing an old backup file from time machine that was probably created when I used TM before I got the external Lacie.

I did notice that Photoshop CS4 told me that the graphics driver was wrong, so I don't what thats all about. Never heard of updating a graphics driver on a Mac.

One thing folks upgrading their computers OS should always always always check first is...the compatibility of their existing software with the version of the OS they are upgrading to. In this case the computers OS was being upgraded from 10.6.8 to 10.8.2.

According to my research...Adobe Photoshop CS4 "has some problems with Mountain Lion". Which basically means Photoshop CS4 is not 100% compatible with OS 10.8.x (Mountain Lion). So this driver message that is being encountered may be related to this.

I just looged into my Adobe Supoort Account and according to Adobe's support forum...

"There are no known issues affecting compatability with OS X 10.8 (Mountain Lion) and Photoshop CS4. As always, make sure you back up your hard drive before you update your operating system, but there should be no problem using Photoshop CS4 when you upgrade!

Have to wait and see when I reboot... maybe it'll find the correct driver. Here's what the pop-up said:

Photoshop has encountered a problem with the display driver, and has temporarily disabled GPU enhancements. Check the video card manufacturer's website for the latest software.

GPU enhancements can be enabled in the performance panel of Preferences.

I'll mess around and see what develops. Go figure. Not related to Photoshop or my CS4 suite... I'm trying to _move_ some folders from my root HDD to my USB drive and they won't go. The USB drive is formatted NTFS, so do I need that Mac NTFS App to do this?

Seems to be a mixed message to me:

- Adobe says no issues between Photoshop CS4 and OS 10.8.2.
- The computer message seems to indicate that there is a problem.

Assuming Adobe Photoshop CS4 is up to date...and unless something else can be found to be at fault...there would seem to be a problem between Photoshop CS4 and OS 10.8.2 (regardless what Adobe says).

Yeah Nick... I agree. But it did allow me to go into preferences and click it back on. And I've been using PS for an hour and saving files in three different formats... no hiccups. Test by fire will be a reboot tomorrow and then restart PS.

Now if I can only figure out why I can't move folders or files to my USB drive.
